This publication outlines the main aspects and issues to be considered when developing and improving in–service inspection effectiveness in nuclear power plants (NPPs). It also provides a status of in-service inspection practices in NPPs in selected IAEA Member States, evaluating criteria for effective traditional in–service inspection and introducing the concept of risk–informed in–service inspection. The strategies for improving in–service effectiveness discussed in this publication consider the entire framework of in–service inspection, including effective selection of the proper inspection scope, inspection interval and non-destructive examination efficiency.
